SPEGIFICATION forming part of Letters Patent No. 746,528, dated December 8, 1903.

Application filed'August 14,1903. Serial No. 169.513. (No model.)

To atZZ whom it may concern.-

Be it known that I, GEORGE W. LARISON, a citizen of the United States, and a resident of Lincoln, in the-county of Logan and State of Illinois, have invented a Combined Roller and Harrow, of which the following is a specification.

This invention relates to a combined roller and harrow intended primarily forthe cul: tivation of young corn by rolling and harrowing the ground between the rows of growing plants.

In the cultivation of young corn it is cus: tomary to roll the ground between the rows and then harrow it, and unless the harrow immediately follows the roller the ground is liable to bake orform a hard crust, especially if a rain intervenes, and in such event when the harrow is used the crust is broken into clods which frequently destroy the plants. follows the roller, it results not only in more effectually destroying the Weeds, but also leaves the earth between the rows soft and mellow. It is advantageous, therefore, to combine the roller and harrow so that the two operations may be performed at the same time, and it is the purpose of my invention to form this combination in such manner as to be most effective and provide for readily and conveniently throwing the harrow out of operation without requiring the driver to leave his seat.

The invention consists in the particular construction and combination of parts, all as will be hereinafter fully set forth, and specifically pointed out in the appended claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is aside elevation illustrating a combined roller and harrow constructed in accordance with my invention, the harrow being in its lowered position to operate upon the ground in the rear of the roller. Fig. 2 is a similar view and in which the harrow is swung upward or elevated out of operative position. Fig. 3 is a plan view of Fig. 1. Fig. 4: is a detail sectional viewof the hinge connection between the roller and harrow.

Similar-letters of reference indicate similar parts in all the figures of the drawings.

Referring to said drawings, the letter A designates the roller, and B the harrow, which When the harrow immediately are of the usual construction,but are connected together in a peculiar manner, so that the harrow will be drawn in the rear of the roller and permitted a slight rocking motion and the machine provided with means by which saidharrow may be maintained in either an operative position directly behind the harrow or swung upward, so that the roller may be used alone'when desired.

The rollerA consists of a rectangular frame composed of the beams a and a, with a central cross-piece a upon which latter the drafttongue a is secured. Rollers a are mounted in this frame at each side of the central cross-piece a leaving sufficient space between said rollers so that the latter will operate at opposite sides of the growing plants and. not interfere with the same. The rollers a are provided with gudgeons or short shafts o journaled in the cross-pieces a and a of is movable back and forward upon its supports, so that the position of the driver may be changed with respect to the disposition of the harrow, and in order that this shifting of the drivers seat may beeffect'ed automatically it is connected to the operating-lever S by rods (i said operating-lever being located in front of the seatand fulcrumed in an arched frame e, projecting upward from the drafttongue. This lever is provided with the usual sliding pawl s, engaging a segment-rack e for holding said lever in an adjusted position, the latter also serving to raise and lower the harrow, as hereinafter described.

The harrow B consists of a frame, as is usual, carrying the teeth'b,the latter being spaced apart at the centerof the harrow, so as not to operate too near the growing plants. The harrow is llingedly connected to the roller-frame by means of links f, pivoted to the harrow between ears I) thereon and to the roller-frame by a transverse shaft g, supported at thelower ends of short links h, the latter being pivoted at their other ends in eye-plates h, secured to the under side of the roller-frame. In addition to the linksf and forming part of this hinge connection are supplemental links or platesf, which are disposed at substantially right angles to the links f, said supplemental links or plates being pivoted to cars b on the harrow a short distance in rear of the ears Z) and at their forward ends slidable upon the aforesaid links fand shaped at this end to engage the shaft g when the harrow is thrown to an elevated position. For this latter purpose the forward end of the plate f is cut away centrally to provide a tongue f bent slightly upward and adapted to bear against the face of the link and provide one of the shaft-engaging members, while the terminal portion of said end is bent outward and upward in rear of the link to form the other engaging member, the linkfpassing through the opening in the rear of the tongue. It will be observed that this plate f is free to ride upon the link when the harrow is lowered, permitting a rocking movement of said harrow, and that when the.

harrow is elevated serves to support the same at a distance above the ground, acting as a fulcrum when the harrow is swung upward. The ears b and b on the harrow and to which the link and plate are respectively pivoted are preferably connected by a plate f so that when the harrow is in its elevated position a triangular-shaped hinge connection is provided to firmly support said harrow. To further elevate the harrow above the ground, the shaft g, upon which it is directly supported, is raised, and for this purpose said shaftis connected to the lower end of a plate t', extending upward and over the rear part of the drafttongue to a staple i, to which latter it is pivoted. Under this plate is arranged a cam-plate j, projecting from a transverse shaft mounted in ears a and having cr'anksj, to which latter are connected links Z, pivoted at their other ends to the lever S, near the fulcrum thereof.

At the central portion of the harrow are secured ears m, forming bearings for a transverse shaft m, to which is pivoted a plate at, bent upon itself to provide an elongated loop n, in which travels a roller 0 at the rear end of a lever 0', which latter is fulcrumed on the shaft g, suspended from the roller-frame. A linkp is connected to near the outer end of the lever 0 and atits opposite end is pivoted to the lower end of the operating-lever S, and by means of this link and aforesaid connections the harrow is raised and lowered upon the operation of the lever.

To one side of the connecting-loop n is attached a spring-catch r, having an offset or engaging portion T, which projects into the loop and is adapted to engage the roller 0 of the lever 0. Said conneeting-loop permits the harrow tobe tilted forward after it is elevated, and when tilted forward the catch wilengage the roller and hold the harrow in such forwardly-tilted position.

It will be understood that the rollers and harrow are adapted to cultivate the ground at opposite sides of a row of growing plants and that the horses are hitchedlat'opposite sides of the draft-tongue, so as to walk between the rows.

In the operation of the combined roller and harrow the lever S is thrown forward so as to lower the harrow to the ground, and it will be dragged in rear of the roller, whereby in the cultivation of corn the ground between the rows will be rolled and then immediately harrowed. Now when it is desired to elevate the harrow out of operation it is only necessary to throw the lever S rearward, which will draw upon the connecting-linksp and Z to swing the harrow upward upon its hinge connections f and f and will also raise the shaft g to further elevate the harrow and parts carried thereby. Simultaneously with this operation the seat, through the intervention of the connecting-rods 61 is moved forward, so that the weight of' the rider will be shifted to counterbalance the weight of the elevated harrow. When the harrow is elevated, as shown in Fig. 2 of the drawings, it will be supported from the roller-frame some distance above the ground, so as not to be injured during transportation of the machine from place to place or while the roller is being used alone.

The relative sizes of the roller and harrow may be changed, as well as the construction of same, as it will be understood that my invention contemplates the combination of the roller and harrow in a single machine that shall be of light draft and easily operated.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
